The courses of stone in the south wall usually run from three feet six inches to three feet nine inches in height; but between the Double Gate and the Triple Gate there is a course described by Captain Wilson, from five feet ten inches to six feet one inch high. Captain Warren found that this course, with some breaks, is continued to the south-east angle, and thence runs north along the east wall for twenty-four feet. The length of this course in the south wall is 600 feet; and the coincidence of this number with the measurement of the temple cloisters, is enough to suggest that we may here have a clue, especially since, through the rising ground under the Triple Gate, this is the first course of stones which could be carried uninterruptedly through from east to west. Captain Warren, following this clue, not only found, after numerous examinations underground, that a perpendicular dropped from the most westerly stone of this course would pretty well divide the wall into two parts of different character, but that the rough stones to the west of this line resemble those at the north-east angle, thus far favouring the conclusion that these were the parts added by Herod.[33] The Triple Gate is in the middle of this six feet course of stones, thus agreeing with the description of Josephus, that the south front of the temple had 'gates in its middle,' an expression which some have tried to reconcile with the existence of the Huldah and Triple Gates, at about equal distances from the angles and from one another, or have construed as applying to the Huldah Gate alone, which is, however, 365 feet from the south-west angle. Under the Triple Gate the rock, as already stated, is highest, and notwithstanding that the slope is greater to the east than to the west, there would thus be an appearance of symmetry in the wall which it could not have if standing entirely west of the Triple Gate. It is worth notice also that at the Huldah Gate, where, on this view, the temple would terminate to west, the wall of the city, coming up from the south, now abuts, indicating that the south-west angle of the Haram is less ancient than the original city wall at this part, and the city wall less ancient than the south Haram wall east of Huldah Gate.
